Amateur radio band

from Wikipedia, the free encyclopedia
Band selector switch on a Collins shortwave transceiver

An amateur radio band is any frequency band that is assigned to the amateur radio service or the amateur radio service via satellites .

The bands are named after the wavelength of the frequencies. The wavelength results from dividing the speed of light (299,792,458 m / s) by the frequency (in Hertz ). For example, the 160 meter band stands for the range from around 1800 to 1900 kHz and the 80 meter band for the range from 3500 to 3800 kHz. For historical reasons, however, the names are not exactly exact, for example in the 40-meter tape .

history

The US Radio Act of 1912 restricted amateur radio stations to wavelengths shorter than 200 meters. At that time, these frequencies were judged to be only suitable for local ranges. After radio amateurs showed that intercontinental connections are possible with little effort on shortwave (see Léon Deloy ), other radio services reported their needs and radio amateurs were further restricted.

The first amateur radio bands were assigned to radio amateurs internationally in the World Radio Treaty (Washington, 1927).

Frequency ranges in Germany

A special feature in Germany are the frequencies within the amateur radio bands in accordance with the Amateur Radio Act (AFuG) as allocated if the radio amateur is allocated a call sign without the need for a further frequency allocation, as is the case with other radio services. The Amateur Radio Ordinance (AFuV) allows amateur radio operations in the following frequency ranges with the following parameters:

SAT Frequency bands are also assigned for amateur radio service via satellites . Any given direction of transmission must be observed.
1 In the frequency range 50–52 MHz, amateur radio broadcasting is also possible subject to certain conditions.
2 Television broadcasts in the broadcast types C3F, H3F, J3F, R3F are only permitted on the frequencies 433.745 and 434.250 MHz and without sound transmission, whereby the band limit of 439.1 MHz may not be exceeded.
